From 5dfbd7bad8b3db6034e6bdcb449f08ec848e64fd Mon Sep 17 00:00:00 2001 From: Jaehoon Chung Date: Thu, 30 Mar 2017 21:29:58 +0900 Subject: [PATCH] board: samsung: trats: remove the unnecessary codes These codes are unnecessary, because max8997 should be initialized with dt-file. Remove max8997_init() function.
